ACCU-ND technology blocks infrared light and limits rust-colored casts in photo and video shoots. The optical glass features multiple anti-reflective coatings, while water and oil repellent treatments prevent water spots and fingerprints.

The ultra-thin aluminum frame reduces vignetting risk even with wide-angle lenses, and the front thread allows for stacking multiple filters. Common applications include extending exposure times to achieve motion blur in landscape photography, or using wider apertures in bright ambient light for video and cinematography.

Also known in the industry as the Hoya IRND 1000 67 mm, the Hoya IRND1000 ND filter fits lenses with a 67 mm front thread. For density, treatment details, and box contents, refer to the specifications table.
